This commit will add the ability to create custom bots in the form of
automatically prepending additional bot-specific context to your chat
session. A new `chat` CLI argument will be added allowing users to
provide the name of an existing bot. For example:
```
llm chat -b "My Bot"
```
An additional `bot` CLI is added for creating and removing bots.
Closes#13
At the end of each sesssion the conversation is stored to a directory
(defaulting to `.history` in the currrent working directory) as a JSON
object. Note, the session must be ended by sending the quit message (/q)
for the conversation to be saved. Ctrl+C will not work.
Linting checks are performed using Ruff, Mypy, and Pydocstyle. Code
formatting is performed using Black and Isort. A Makefile is also added
with linting and formatting commands for convenience.
This commit implements a basic interface to hold a conversation with
OpenAI's GPT models via their API, using OpenAI's Python SDK. In
addition to this interface, the commit incorporates Pydantic for
managing settings via environment variables.
